Are MetaZoo Booster Packs Weighable?

I am pleased to inform you that, no, MetaZoo booster packs are not weighable. This includes, but is not limited to Cryptid Nation 1st Edition and Nightfall 1st Edition booster packs.

The reason for this is because every booster pack contains either a full holographic or a reverse holographic card; both of which are printed on full foil sheets.
